3. What is cloud computing ?
The cloud allows users to access the same files
and applications from almost any device
because computing processes and storage take
place on servers in a data center and not locally
on the user's device.
4. WHAT IS FOG COMPUTING ?

The fog extends the cloud to be closer to the things that produce
and act on IoT data .
These devices, called fog nodes, can be deployed anywhere with
a network connection.
Any device with computing, storage, and network connectivity
can be a fog node.
Examples include industrial controllers, switches, routers,
embedded servers, and video surveillance cameras.
In simple, its a connection between cloud and your internal
network , that processes and stores the data .

6. WHY DO WE NEED FOG COMPUTING?
sFog computing -R. BELHAJALI- 6
Low-Latency Network Connections : Low-
Latency Network Connections between devices
and analytics endpoints.
Low Bandwidth : reduces the amount of
bandwidth needed compared to if that data had to
be sent all the way back to a data center or cloud
for processing.
Analysis of Data : It can also be used where
there is no bandwidth connection to send data.
7. HOW DOES FOG COMPUTING WORK?
Fog computingl -R. BELHAJ ALI- 7
A fog computing fabric can have a variety of
components and functions. It could include fog
computing gateways that accept data IoT devices have
collected. It could include a variety of wired and
wireless granular collection endpoints, including
ruggedized routers and switching equipment. Other
aspects could include customer premise equipment
(CPE) and gateways to access edge nodes. Higher up
the stack fog computing architectures would also touch
core networks and routers and eventually global cloud
services and servers.
8. FOG COMPUTING VS CLOUD COMPUTING
Fog computingl -R. BELHAJ ALI- 8
Cloud – A Network that connects same
network or different Networks.
Fog – A part of the network that connects
same Cloud and Local Datacenter.
Fog computing is a part of Cloud
Computing.
10. FOG COMPUTING VS EDGE COMPUTING
fog computing vs edge computing -R. BELHAJJAli- 10
Fog computing as the way data is processed from
where it is created to where it will be stored.
Edge computing refers just to data being processed
close to where it is created.
Fog computing encapsulates not just that edge
processing, but also the network connections needed to
bring that data from the edge to its end point.
edge computing is a component, or a subset of fog
computing.
11. Conclusion
fog Computing -R BELHAJ ALI- 11
❑Fog Computing aims to reduce processing burden of
cloud computing. Fog computing is bringing data
processing, networking, storage and analytics closer to
devices and applications that are working at the network’s
edge. that’s why Fog Computing today’s trending
technology mostly for IoT Devices.
